It is designed for buffering data between two clock domains or bus-width converters in 5 V logic systems. The 50 ns access time and 15 MHz data rate suit moderate-speed applications like printer buffers, industrial controller data capture, or telecom line-card packet queues. The part operates from a 4.5 V to 5.5 V supply and is specified over the commercial temperature range of 0°C to 70°C, so it is intended for indoor, non-extreme environments. ## 50 ns access time — what it means for bus timing The 50 ns access time is the time from read-enable assertion to valid data on the output bus. In a typical asynchronous read cycle, the host controller must wait at least 50 ns after strobing the read line before latching data. This sets a ceiling on the system clock or cycle time: a 50 ns access time limits the read cycle to roughly 20 MHz maximum if you account for setup/hold margins. For a 15 MHz data rate (the maximum guaranteed throughput), the 50 ns access time is well within the available cycle budget, leaving margin for bus propagation delays and logic timing. ## 256 x 9 depth and width — buffer sizing The 256-word depth by 9-bit width is a common size for byte-wide data plus a parity or control bit. The 9-bit width allows storage of 8-bit data with an extra bit for parity, tag, or flag. The 256-word depth provides a 256-byte buffer (plus parity), which is sufficient for short data bursts in applications like interrupt-driven UART buffering, small packet assembly, or rate-matching between a slow ADC and a fast DSP. The FIFO supports depth and width expansion (cascading multiple devices) for larger buffers. ## Package and footprint: 32-PLCC (J-Lead) The SN74ACT7200L50RJ comes in a 32-lead PLCC package (J-lead form factor), supplier device package 32-PLCC. The J-lead is a surface-mount style with leads bent under the body, requiring a PLCC socket or a reflow profile compatible with J-lead solder joints. The package is not a standard SOIC or QFP, so verify the board footprint matches the 32-PLCC land pattern. The part is marked as RoHS non-compliant, meaning it contains lead in the solder finish — check your assembly line's exemption status for leaded components. ## Lifecycle and sourcing reality However, it is RoHS non-compliant, which may limit its use in new designs bound for RoHS-regulated markets. If you need a lead-free alternative, the SN74ACT72241L20RJ and SN74ACT72231L20RJ are higher-speed siblings (20 ns access time) in the same 74ACT family, but verify pin-compatibility and functional equivalence before substituting.","metaTitle":"SN74ACT7200L50RJ Asynchronous FIFO, 256x9, 50ns, 32-PLCC","metaDescription":"TI SN74ACT7200L50RJ asynchronous FIFO, 2.25K (256 x 9) memory, 50ns access time, 15MHz data rate, 4.5V-5.5V supply, 0°C-70°C, 32-PLCC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Bulk","Function":"Asynchronous","Data Rate":"15MHz","Access Time":"50ns","Memory Size":"2.25K (256 x 9)","FWFT Support":"No","Mounting Type":"Surface Mount","Expansion Type":"Depth, Width","Package / Case":"32-LCC (J-Lead)","Bus Directional":"Uni-Directional","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5 V ~ 5.5 V","Operating Temperature":"0°C ~ 70°C","Retransmit Capability":"Yes","Current - Supply (Max)":"80mA","Supplier Device Package":"32-PLCC","Programmable Flags Support":"No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.01","stockQuantity":0,"priceTiers":[{"qty":150,"price":"$2.01000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c28bc5e20fbc5f235240ce248c7fc3e4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of SN74ACT7200L50RJ?","answer":"The access time is 50 ns, measured from read-enable to valid data output."},{"question":"What is the equivalent or replacement for SN74ACT7200L50RJ?","answer":"Higher-speed siblings in the same 74ACT family include the SN74ACT72241L20RJ and SN74ACT72231L20RJ, both with 20 ns access time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74ACT7200L50RJ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74ACT7200L50RJ when reusing this data.
